Description
FIELD OF THE INVENTION

The disclosure relates to compositions for use on keratinous substances. In particular, it relates to a composition and methods for styling the hair.

BACKGROUND

Compositions for styling the hair are known, such as, for example, hair spray compositions, hair gels and mousses, hair volumizing compositions, hair smoothing creams, lotions, serums, oils, clays, etc. The goals of many hair styling compositions include holding or fixing the hair in a particular shape, imparting or increasing volume of the hair, smoothing the hair, and/or decreasing or eliminating the appearance of frizz.

Drawbacks associated with current products for styling the hair include that the product can be sticky or tacky and/or can produce a film that imparts a sticky or tacky feel. Moreover, hair styled with current products can be stiff and/or “crunchy” in that the film is hard and brittle resulting in a crunching feel or sound when the hair is touched, which is undesirable for most consumers.

Current products for styling the hair typically include water-soluble film-forming polymers. Depending on the chemical make-up of these polymers, they may be either soluble in water, or they may be water insoluble polymers which are made water soluble via various chemical modifications, such as neutralization. Solutions comprising these polymers tend to be viscous, and often as the concentration of the polymer increases, its viscosity rapidly increases. In styling applications, as the solvent evaporates, the polymer solution becomes thicker on the hair surface, resulting in a sticky or tacky film. These products also tend to exhibit problems with product spreadability, hair manageability, and humidity resistance, which is especially a problem in hot and humid environments.

Particularly, while previous compositions comprising latex polymers may provide clean properties to the hair given its anionic nature, the clean properties can translate into difficult application and/or distribution of the product, quick absorption, dryness, and/or possibly static in the hair. The presence of film formers can also leave the hair with a stiff, crunchy, and/or sticky feel. Often, traditional silicones may be used to overcome the brittleness and stiffness caused by the film, however this tends to make the hair feel greasy and oily. Alternative conditioning agents, such as non-ionic silicones and humectants, can actually plasticize the film produced by the product, thus affecting its high humidity curl retention, and creating build up, which weighs down the hair.

It has now been surprisingly and unexpectedly discovered that combining at least two latex polymers, wherein at least one latex polymer is a film-forming polymer, with at least one aminofunctional silicone, at least one amphoteric surfactant, at least one alkylpolyglucoside, at least one anionic thickening agent, produces a composition that exhibits excellent conditioning properties in wet and dry stages of hair while maintaining desirable care benefits and styling and shaping properties. Such compositions can allow for a clean, natural, and/or “invisible” feel; a lack of stickiness; frizz control; high humidity resistance; curl and/or wave definition; and styling hold with or without the use of heat. Some compositions may be useful in hair-styling applications wherein styling benefits such as natural look, curling or straightening, and/or styling hold are imparted to hair.

Solvent

The compositions according to the disclosed embodiments may further comprise at least one solvent. In certain embodiments, the at least one solvent may be chosen from water, at least one cosmetically acceptable organic solvent, or a mixture of water and at least one cosmetically acceptable organic solvent. In various embodiments, the cosmetically acceptable organic solvents may be water-miscible, e.g. a mixture capable of forming at 25° C. a homogeneous mixture that is transparent, or substantially transparent, to the eye, chosen from lower monoalcohols, such as those containing from about 1 to 5 carbon atoms, for example ethanol and isopropanol; polyols, including glycols, such as those containing from about 2 to 8 carbon atoms, for example propylene glycol, ethylene glycol, 1,3-butylene glycol, dipropylene glycol, hexylene glycol, and glycerin; hydrocarbons, such as, for example, isododecane and mineral oil; silicones, such as dimethicones, cyclomethicones, trisiloxane, and cyclopentasiloxane; or mixtures thereof.

In certain embodiments, the latex polymer particles are not soluble in the solvent of the composition, and thus remain in particulate form while in the composition and after evaporation of the solvent. For example, in embodiments where the composition comprises alcohol as a cosmetically acceptable organic solvent, the latex particles may remain in particulate form upon evaporation of the alcohol, such as once the composition is applied to a substrate.

According to various embodiments, the at least one solvent may be present in an amount ranging up to about 95% by weight, from about 1% to about 90% by weight, or from about 5% to about 80% by weight, relative to the total weight of the composition.

Propellant

The compositions according to the disclosed embodiments may further comprise at least one propellant. As used herein, the term “propellant” is meant to indicate a liquid or gas that is packaged with the composition in a device under pressure, which serves to dispense the composition from the device with force and/or facilitate or enhance the foaming of the composition.

Nonlimiting examples of propellants that are suitable for use include gases usually used in the cosmetic field, in particular optionally halogenated volatile hydrocarbons, for example n-butane, propane, isobutane, or pentane, and halogenated derivatives thereof; carbon dioxide, nitrous oxide, dimethyl ether, hydrofluorocarbons, and nitrogen, alone or as mixtures.

In certain embodiments of the disclosure, the propellant is chosen from alkanes and in particular from n-butane, propane, and isobutane, and mixtures thereof.

According to various embodiments, the propellant is under pressure, and at least partially in liquid form.

In certain embodiments, the total amount of propellant ranges from about 1% to about 30% by weight, relative to the weight of the composition, such as from about 2% to about 15% by weight relative to the weight of the composition.

Compositions

The compositions according to the disclosed embodiments may further comprise additional components that are typically used in hair styling compositions. Such components are known to those of skill in the art, or are within the ability of those of skill in the art to determine depending on the particular application, such as, for example, organic amines, carbonate compounds, emulsifying agents, fillers, pigments, conditioning agents, moisturizing agents, additional viscosity or thickening agents, shine agents, sequestering agents, fragrances, preservatives, pH modifiers/neutralizing agents, stabilizers, propellants, or mixtures thereof.

In various embodiments, the composition described herein may have a pH ranging from about 2 to about 9, such as about 3 to about 8, or about 5 to about 7.

In some embodiments, the compositions are in the form of hair styling compositions, in any form, such as, for example, a gel, a foam, a lotion, an emulsion, or a liquid that may be sprayed onto or otherwise applied to the hair. In certain exemplary embodiments, the composition may be provided in the form of a mousse, or a spray.

In various embodiments, the composition is a hair styling composition. According to various embodiments, by “hair styling composition” the composition is meant to be applied to hair on the head other than eyelashes and/or eyebrows. Hair styling compositions and mascaras are sometimes distinguishable based on the components of the compositions and/or the effects of the compositions when applied. In some embodiments, at least one component of a hair styling composition is not compatible for use in a mascara. In other embodiments, at least one component of a mascara is not compatible for use in a hair styling composition.

According to some embodiments, the composition is not applied to the eyelashes and/or eyebrows. In certain embodiments, the composition is not a mascara.

In certain embodiments, the composition may be applied to the hair by first applying to the hands, and then contacting the hair with the hands. In other embodiments, the composition may be applied directly onto the hair, such as by spraying. In other embodiments, the composition may be applied to wet or dry hair. The compositions may, in various embodiments, be applied to the hair as a leave-on treatment.

In one embodiment, the hair is allowed to air dry after application of the composition, and no heat is applied to the hair.

In one embodiment, the hair is allowed to air dry after application of the composition, and is styled or shaped with no heat being applied to the hair.

Styling or shaping the hair may involve the use of devices on hair such as a brush, a comb or running the fingers of the hand through the hair.

In various embodiments, the application of an external stimuli, such as heat, may be desirable as part of the hair styling process. By way of example only, before, during, or after the composition is applied to wet or dry hair, the hair may optionally be further treated with an external stimuli, for example with heat ranging from about 25° C. to about 250° C. In at least certain embodiments, the hair may also be shaped or positioned as desired while exposed to external stimuli, such as while heated or exposed to heat.

Professional and consumer heating tools can be used as a means to deliver heat or an elevated temperature to the hair. The heating tools can generate heat through electrical current or heating lamps. Depending upon the desired style, these tools include, but are not limited to, heaters, blow dryers, flat irons, hot combs, hot curler sets, heated crimpers, heated lash curlers, heated wands/brushes, and hood driers or their combinations thereof.

In other embodiments, the hair is allowed to air dry after application of the composition, and no heat is applied to the hair. In yet other embodiments, the hair is allowed to air dry after application of the composition, and styled or shaped with no heat being applied to the hair.

As described, compositions according to the disclosure may impart a film on a substrate, such as on the hair or on the hand during or after application to the hair. A film formed by the composition according to certain embodiments may be surprisingly clean-feeling and not sticky, as with traditional hair styling compositions. Also surprisingly, the composition may impart a film on the hair that leaves the hair relatively natural and clean-feeling, yet has a flexible coating, leaving little to no residue, allows the hair to be bouncy and springy with little to no frizz or flaking, may impart relatively high definition with individualized curls, style control, volume, and/or shine, and/or may allow for relatively long-lasting hold and style memory. Furthermore, in at least certain embodiments according to the disclosure, the compositions are not sticky or tacky. A user of hair compositions according to various embodiments described herein may thus feel that the composition is not perceptible or is “invisible,” yet still effectively style and/or hold the hair. Additionally, the compositions may have effective hair styling and/or hold properties, even in conditions of high, or relatively high, humidity. In at least certain embodiments according to the disclosure, the compositions may be quick-drying, which may allow drying and/or styling time to be reduced, as well as further improve ease of styling and curl retention.

Furthermore, as described, compositions prepared according to the disclosed embodiments may provide for varying degrees of hold to be imparted to a hair style. By way of non-limiting example only, in order to obtain a spiky look to hair of a very short length, a high level of styling hold may be desirable. Or, as a further non-limiting example, in order to obtain a flowing look or to maintain hair curls for hair of medium length or longer length, a light to medium level of style hold may be desirable. By altering the weight ratio of the first and second polymers, it is possible to formulate compositions having high levels of style hold, medium to high levels of style hold, medium levels of style hold, or light to medium levels of style hold.

In at least certain embodiments, a film formed by the compositions described herein may be clear and/or stable. In such embodiments, phase separation and dramatic aggregation are minimized.

In addition, hair styled or treated with compositions according to the disclosure, in at least certain exemplary embodiments, may be hydrophobic, may appear less frizzy, and/or may be less prone to breakage, relative to hair subjected to the same conditions but not having been styled or treated with a composition according to the disclosure.

It should be noted, however, that compositions and films, as well as hair to which the composition or film has been applied, according to the disclosure may not have one or more of the herein-referenced properties, yet are intended to be within the scope of the disclosure.

Also disclosed herein are methods for styling the hair, said methods comprising applying a composition according to the disclosure to the hair, either before, during, or after styling the hair. One or more steps of treating the hair with an external stimuli, such as heat, before, during, or after the composition has been applied to the hair are also contemplated. Additional methods comprise applying a composition according to disclosure to dry hair to achieve a desired shape.

It is to be understood that both the foregoing description and the following Examples are exemplary and explanatory only, and are not to be interpreted as restrictive of the disclosure. Moreover, it should be understood that various features and/or characteristics of differing embodiments herein may be combined with one another. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the scope of the disclosure. Other embodiments will be apparent to those skilled in the art from consideration of the disclosure and practice of the various exemplary embodiments disclosed herein.

It is also to be understood that, as used herein the terms “the,” “a,” or “an,” mean “at least one,” and should not be limited to “only one” unless explicitly indicated to the contrary. Thus, for example, the use of “a surfactant” is intended to mean at least one surfactant unless the context clearly indicates otherwise.

It should be understood that all patents and published patent applications referenced are incorporated herein in their entireties.

While various features, elements or steps of particular embodiments may be disclosed using the transitional phrase “comprising,” it is to be understood that alternative embodiments, including those that may be described using the transitional phrases “consisting” or “consisting essentially of,” are implied. Thus, for example, implied alternative embodiments to a method that comprises A+B+C include embodiments where a method consists of A+B+C and embodiments where a method consists essentially of A+B+C. As described, the phrase “at least one of A, B, and C” is intended to include “at least one A or at least one B or at least one C,” and is also intended to include “at least one A and at least one B and at least one C.”

All ranges and amounts given herein are intended to include subranges and amounts using any disclosed point as an end point. Thus, a range of “1% to 10%, such as 2% to 8%, such as 3% to 5%,” is intended to encompass ranges of “1% to 8%,” “1% to 5%,” “2% to 10%,” and so on.

All numbers, amounts, ranges, etc., are intended to be modified by the term “about,” whether or not so expressly stated. Similarly, a range given of “about 1% to 10%” is intended to have the term “about” modifying both the 1% and the 10% endpoints.

Unless otherwise expressly stated, it is in no way intended that any method set forth herein be construed as requiring that its steps be performed in a specific order. Accordingly, where a method claim does not expressly recite an order to be followed by its steps or it is not otherwise specifically stated in the claims or descriptions that the steps are to be limited to a specific order, it is no way intended that any particular order be inferred.

It should be understood that compositions according to various embodiments of the disclosure form a film when applied to a substrate. However, the various properties of the film described herein are intended to include any film provided by compositions according to the disclosure, regardless of whether the film is attached or bonded to the substrate or not. By way of example only, once the compositions are applied to a substrate and a film is formed, the film may subsequently be removed in order to evaluate properties such as strain and Young's modulus.

Unless otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present disclosure. For example, the term “about” can mean within 10% of the indicated number (e.g. “about 10%” means 9%-11% and “about 2%” means 1.8%-2.2%), such as within 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1%, according to various embodiments.

Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, unless otherwise indicated the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. The example that follows serves to illustrate embodiments of the present disclosure without, however, being limiting in nature.

It is understood that when an amount of a component is given, it is intended to signify the amount of the active material, unless otherwise indicated.

The compositions and methods according to the present disclosure can comprise, consist of, or consist essentially of the elements and limitations described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise known in the art.

According to Tables 1 and 2 above, Examples 1, 2, 3, 6 and 7 and Comparative Examples 4 and 5 were prepared based on the following protocol:

A tank contained water. Polyacrylate-3 was added to the tank and the ingredients in the tank were mixed until uniform. Then, a neutralizing agent was added, at which point the batch thickened and turned clear. Surfactants and polymers, including acrylates copolymer and polyurethane-34, were added to the batch. Then, additional surfactants and aminofunctional silicones were added to the batch in Examples 1-3; additional surfactants and non-aminofunctional silicones were added to the batch in Comparative Example 4; and additional surfactants were added to the batch in Comparative Example 5. Solvents, preservatives, and other additional components were added to the batch. The batch was mixed between the additions until it was uniform. Each of the compositions containing propellants (isobutane and propane) was packaged in respective vacuum-sealed pressurized cans; propellants were released through a valve into the vacuum-sealed pressurized cans, wherein the propellants and composition could mix together.

Examples 1-3 and Comparative Examples 4 and 5 were then applied to corresponding locks of wet hair and hair on mannequin heads. A panel of experts evaluated the compositions based on ease of application and distribution on the hair. The panel of experts also evaluated the locks of hair based on hair volume, feel of the hair, and conditioning effects. The treated locks of hair were then blow dried with a round brush, and the panel of experts evaluated the dry treated hair based on the same criteria.

Examples 1, 2, and 3, provided great conditioning properties in both wet and dry stages while maintaining a clean feel and high resistance to humidity. The hair locks treated with Examples 1, 2, and 3 had a clean, natural, and/or “invisible” feel and a lack of stickiness.

In contrast, Comparative Examples 4 and 5 did not provide desirable hair care benefits. Specifically, the hair treated with Comparative Example 4 was heavy and had low volume and a greasy feel. Comparative Example 5 imparted a dry and super clean feel to the hair, which led to difficult application and distribution of the product, dryness, and static in the hair. Further, Comparative Examples 4 and 5 did not provide conditioning effects after the treated hair locks were blow dried.

Both examples 6 and 7 imparted to hair a natural/clean feel (no residue, no flaking, not sticky), a touchable feel, frizz control, long lasting natural shape control and lightweight feel to the hair (did not give a heavy feeling to the hair).

Example 6 provided to the hair more flexible hold and additional shine while providing a hold that resulted in a textured look.

Example 7 provided a strong hold and enhanced the natural waves and curls of the hair.
